Precision-ground from solid high-speed steel, these IRWIN HSS PRO twist drill bits deliver a 13.0 mm diameter with DIN 338 compliance and a 118° point angle for fast, clean starts in metal. The set includes 5 bits, each with a straight shank and bright finish, engineered for reliable performance in steel, cast iron, non-ferrous metals, and plastics.

Overview

The IRWIN HSS PRO series represents professional-grade metal drilling. Each bit is manufactured to DIN 338 standards, ensuring consistent geometry and dimensional accuracy. The 13.0 mm size is ideal for larger holes in structural steel, thick sheet metal, and cast components.
